The original paper from which the copy is to a be taken is printed in aconventional manner on -a tabulatontypewriter or other suitable mediumand is backed with" suitable carbon paper while being printed. Theoriginal may take the form of single sheets, fainfold' or continuousroll- The transfer is accomplished by interposing-a ribbon or similarmedium moistened with solvent above the area to be transferred and thenapplying pressure on the ribbon to bring the ribbon, the

' original and theledger sheet or receiving paper together. The solventdissolves a portion of the carbon from the original and deposits'it onthe ledger'sheetm M i m i i The machine includes a table or plate 2|,(Fi

'1) supported between side frames 22 and 23. Upon this table is placedthe ledger sheet to receive the impression. The frames 22 and 23 arerigidly joinedby a lowerpressureI-bar 24. (Fig. 2)

bars 25=and 26 and a motor support plate 21. 5

A motor 28 (Fig. '3) provided to drive the several mechanisms of themachine, is mounted on the plate 21. .The motor,'thro ugh a; pulley andbeltbconnelction 2'9 nd a gear box'30 supported on the plate 21 operatesa short shaft 3| sup- 4o ported in brackets 32 and 33 secured' to theplate '21. Aclutch disc 34 (see also Fig. 4) fast on the shaft 3! isprovided with notches 35' about its periphery with which notches aclutchpawl 36 ,pivot'all'y carried by a. clutch arm 31 fast ona camshaft '3l cooperates. The cam shaft 38 is supported ida'bracket 39secured; to'the plate Q 21 and .in. .the' frame. the shafts 3| and 38.beingin axlal alignment.

The. arm 31 (Fig. 4) and shaft sajajr'e normally 9 held against rotationby an arm 40 fastfon .a

short shaft l'lpivotally supported by the brackets The arm 40 hasa'shoulder 42 which normally lies in the path of the arm 37 and of atail of the pawl 36 thus holding the a shaft 48 journaled in the frames22 and 23.

Also fast on the shaft 48 are two release bars .49 one being locatednear each end of the shaft and being arranged to lie conveniently oneon;

each side of the table 2| (see 1)--.

In order to initiate an operation of the machine the operator depresseseither of the bars" 49 which movement rocks the shaft 48 and armcounterclockwise thrusting-the link 46 toward the right. At thismovement a lever .58. pivotally carried at the right-hand endof thelink- 46 and having a notch engaging the stud 43-,

rocks the arm 44, shaft 4| and arm therewith, removing the shoulder '42from engagement with the arm 31 and the tail of the pawl 36. The pawl,thus freed, is engaged with one of the notches 35 by a spring56. 'Thearm 31 and the shaft 38 make one complete counterclockwise rotation. I

A cam 51, the outline of which is indicated in Fig. 4 by dot and 'dashlines for the sake of cleamess, fast on the shaft 38 adjacent the leverhas a single notch in its periphery cooperating-with a stud 58 on thelever"58. As

soon as the shaft 38 starts to rotate the cam' "51 rocks the lever 50clockwise freeing the arms 44 and 48to a spring 59 which immediatelyrestores these arms to their normal positions. Near the end of therotation the shoulder 42 rocks the pawl 36 out of engagement with thedisc 34 and stops thearm 31 and shaft 38. A

spring pressed retaining pawl 68 prevents retrograde movement or reboundof the arm 31.

If the operator has released the bar 49 before the end of the rotationof shaft 38 the parts top of the stud-13am! it will 'berziecessary'forthe operator -to release the bar-49%F'permitting a. spring 6| (Fig. 4),having-one end 'attached to an arm 62 fast on the shafti48, torestore"the link toward the. left before another operation may be inltiated.---v I redeemed; 'f'i li on which a copy is to be made beneath a trans- 80parent line finder 64 adjust'ably mounted on a 88 located on the table2| with its left edge be-" '10 1, 2, 3, '7; and 8) secured-to a'pair ofspaced j bar supported in a manner to 'be described later. thereon toassistthe operator in the proper positioning of the ledger sheet. Thesheet is neath spring pressed ledger clamps 65 (Figs. 1,

2, 3, and 8), there being four clamps 65 mounted 'on the ledgercarriage.

The ledger carriage includes'ajbar '66 (Figs.

This finder has parallel "lines scribed of the table 2|. A stop bar 18is mounted on the bar 66 to locate the edgeof the ledger when it isplaced in position on the table. The clamps 65 are slidable verticallyin the bars 66 and 18 and are normally urged downwardly to grip thepaper 63 by springs 1| secured to the under side of the bar 66. I

After the ledger sheet is in proper position the; operator depresses thereleasle' bar 49 whereupon theshaft- 38 rotates. Shortly thereafter acam 12 (Fig. 8) permits a spring 13 to rock ;clockwise an arm 14 mountedon 'a shaft 15 supported in the bracket 39 (Fig. 3) and the-side frame23. An arm 16 fast to a shaft 11 (Figs. 3 and: 8) is connectedby a link18 to the arm 14. Also fasten the shaft 11 is a bell crank 19 whoselinkto a bell crank 8| pivoted on a stud projecting from a bracket 9|secured'to the bar 24. A bar 82" supported on the bell-cranks 19 and 8|is normally pressed upwardly against the paper clamps 65 and against thetension of springs 1| by the'cam 12, v

'The clockwise, movement of the arm 14 described above is transmitted bythe link 18 to rock the arm 16, shaft 11, bell crank 19 and due to theconnection 88 the bell crank, 8| counterclockwise to lower the bar 82.This permits the springs 1| to draw the clamps 65 down gripping theledger sheet 63 firmly between said clamps and'the carriage bar 66.

- Shortly after the ledger sheet is gripped, in the manner justdescribed, mechanism now to be described isoperated to shift thecarriage a distance suiiicient to move the selected line from itspositionbeneath the line finder 64 (Fig-6) to a position under apressure bar 83. This mechanism includes a pair of cams 84 (Fig.7)cooperating with a bell crank 85 pivoted on the shaft 15 and which isconnected by a link 86 to an arm 81 fast toa shaft 88supported betweenthe side frames 22 and 23. Another arm 89 also faston the shaft 88pivotally carries at its-free end a lever 99 having. one arm connectedby a link 96 to the rear block 61 of the ledger carriage. A spring 91presses the other from the arm 89-.

As the shaft, 38- rotates, rocked clockwise. which movement through thelink 86, rocks the arm' 81-; shaft 88 and arm 89 in the samedirectioriamovement through the link 96 draws the carriage toward theright '(Figs. 2 7) and toward the rear of theus The Eagerg indie-Ed at3'1-v(F1g" machine .(Flgs. 1 3) for purpose set and 6)--onto whichthetransfer is to be made" is placedon the table 2| with the'first line'inthe case of a new sheet or the next blank line}- forthabove. I

In order to align the typed matter on thev ledger' sheet there is'provideda plurality of index fingers 5| (Figs. 5, 6, 11, and 14)slidablyv mounted on a rod 52 supported betweenthe the bell crank as isoriginal sheet with the proper column on the.

downwardly extending arm is connected by a arm of the lever against astud 98 projecting frames 22 and 23. The ledger sheet 63 (Fig. 14')-- isplaced in position on the table 2| andmanually shifted to positionbeneath the pressure bar 83 at which point it is directly under thefingers 5|. The fingers are now adjusted along the rod 52 to-bring thefingers in line with the limits between-which it is desired to have thetransfer appear as indicated in Fig.'14; '-With the fingers 5| in theirselected positionsthe original sheet is inserted and the first line oftyped matter is positioned as'indicated in'Fig. 14 with the top of 'thetyped matter aligned with the'. bottoms of.

the fingers 5| and the first and last characters in line with thenotches in the left-hand and r right-hand fingers 5| respectively. Thearms m- I (Flg. 11) are now operated to bring the rolls I30 into contactwith the roll I31 thus holding the original sheet I53 in position.

Thebar-ii which supports the line finder 04 (mg. 6) is adjustablysiipported in slots in the side members or plates IN and I02 of themoisture reservoir, to permit adjustment of said bar and the line finder04 toward and away-from the index fingers 5|. The purpose of thisadjustment is to vary the line spacing on the ledger sheet 03. It willbe'remembered that the ledger sheet receives an-invariable movementfromL-line finding position to transfer position. Obviously if the linefinder 64 is adjusted closer to the transfer position the spacing of thelines transferred to the ledger sheet will be increased, and if the linefinder is adjusted farther from the transfer position the line spaces onthe be decreased.

Moistenino device 1 It was stated above that the medium'for applying thesolvent to the area to be transferred ledger sheet will comprises aribbon. This ribbon, indicated at 30v in Figs. 5, 6, and 10, normallyrests in a solvent reservoir comprising a channel member I integral withside members "I and I02 which rest receiver tube I08 so that the end ofthe spout I01 rests on the wick I05. When the machine is in operation itrests with the table 2I at approximately the angle indicated in Fig. 2in which position the level of the solvent is substantially as indicatedby the dotted line I09 (Fig. 6). The purpose of the pad I on the bottomof the reservoir upon which the end of the tube I01 rests is to controlthe level of the solvent in the reservoir. If the end of the tube I01rested on the bottom of the channel member I00 the level of' the solventwould fall until the aperture of I01 was uncovered. Then a sudden rushof liquid would raise the level too high. By use of the pad I05 theliquid is absorbedfrom the supply I06 as it is used maintainingthe-level constant.

The pad I03 (Fig. 6) comprises a length of wick next to the angularplate I04. On top of the wick is a plurality of thicknesses of blottingpaper and finally on the blotting paper is a length of fabric having avertical pile or nap. It has been found that this arrangement ofmaterials provides the correct degree of moisture for the ribbon 99 andthat the nap obviates the tendency of the ribbon to stick to the pad asis the case when a comparatively smooth fabric is used. The purpose ofthe piled fabric I03 is to control the amount of solvent reaching theribbon. Also the pile permits the entire length of ribbon to leave thepad when it is moved to moistening position. 'If the pad I03 wereprovided with a flat surface of closely woven or fabricated material thecenter portion of the ribbon would have a tendency to adhere when theribbon is moved and the snap of this portion of the ribbon would throwsmall drops of solvent onto the sheet I53 causing the carbon to run andresulting'in a smudged copy.

otally supported in the end plates MI and I02. Springs II2, one oneach-arm IIO support and tension the ribbon between said arms. Theribbon,- as previously stated, normally occupies a position in contactwith the pad I03 it being pressed thereagainst by the weight of a coverII3 fast on a shaft II4 journaled in the plates IM and I02. At theproper time the cover H3 is raised and the ribbon 39 is swung to theposition in which it is indicated by dotted lines 33' (Fig 6). Themechanism for raising the cover H3 and operating the ribbon arms IIIwill now be described.

Referring to Fig. 10, a cam II5 on the shaft 38 rocks an arm 6 on theshaft 15 counterclockwise against the tension of a spring I33 and by aconnection II1 rocks a lever III cl0ck-' wise. The lever H3 is pivotedon astud projecting-from a bracket I34 secured to the bar 24 I andl hasits upper end formed to cooperate with a stud H9 carried on the free endof an arm I20 fast on the cover shaft II 4. The clockwise movement ofthe lever IIO rocks the arm I20 and the shaft II4 counterclockwiseagainst the tension of a spring I3I to raise the cover II3 The ribbon 9ais carried, tightly stretched, between arms IIO (Fig. 5) fast on ashaftIII pivfrom the position shown in Fig. 10 to the position shown in fulllines in Fig. 6.

When the cover H3 is partly. open the lever H8, continuing its clockwisetravel, strikes a stud I2I on a gear sector I22 free on the shaft .4rocking said sector counterclockwise against the tensionof a spring I32.The sector I22 meshes with a gear I23 fast on the shaft III, the gearI23 and shaft III being thus rotated.

clockwise to swing the ribbon arms IIO to the position indicated bydotted lines at III! (Fig. 6) in which/position the ribbon 39 occupies aposition 39' in the downward path of a platen I24 mounted in thechanneled lower edge of the pres sure bar 83, just before said barstarts its downward movement.

- Pressure bar being disposed near each end of said shaft. The

right-hand arm I21 (Fig. 3) is connected by a link I29 (see also Fig. 2)to one arm of a-bell crank I30 pivoted on the shaft 15. A pair of cams I36 on the shaft 38 cooperates with antifriction rollers on the bellcrank I30 to rock it first clockwise and then counterclockwise tonorinal. The clockwise movement of the follower through the link I29,arms I21 and links I lowers the pressure bar 83 to cause the transferand the counterclockwise movement of said bell crank I through the samelinkage raises the pressure bar to normal I Paper feed-originalReferring to Figs. 1, 6, and 7, a feed roll I31 is secured on a shaftI38 journaled in the frames 22 and 23. A plurality of pressure rolls I39each wheel I44 (Fig. 7) with which cooperates a spring pressed feed pawlI45 carried on anarm I46free on the shaft I38. A I41, connects-the armI46 to an armI48 pivotally supported on the frame 22. An anti-frictionroller 1149 normally 1 'frests' on the flattened end of an arm I50secured t the shaft 88.:

It will be remembered that the shaft 88 rocks first, clockwise and thenback to normal position under the influence of the cams 84, the arm I50making a similar excursion (Fig. .7). When the arm I50 rocks clockwisefrom beneath the roller- I49 a spring II draws the arm I48 and link I41I downwardly rocking the arm I46 clockwise to remade, indicated at I53(Figs..6 and ll), is in-; serted over a shield I54 passing beneath theres-' ervoir I00, between a bar I55 and a plate I56; between the feedroll-I31 and the rolls I39 and over the arms I40. The shield I54 mountedon a rod I51 extending between the plates I01 and I02 and is furthersupported by brackets I58 (only onebeing shown) secured to said plates.The bar- I55 is carried between two arms I59. (see alsoFig. 1) pivotedon a shaft I60 supported inthe brackets I43. A spring I6I holds the armsI59 and the bar I55 in the position in which they-appear in full linesin-Fig. 11. The plate I56 is secured to the shaft I60 and is normallyheld in the'position in which it is shown in full lines in Fig. 11 bysprings I62 (Fig. 1) attached .to levers I63-which are also secured onthe shaft I60.

In order to insert an original copy sheet a pair of arms I64 (Fig. 11)is rocked counterclockwise-i These arms are secured one on eachend of ashaft I65 journaled in the brackets I43 and which shaft is provided withnotches into which fit the arms I40. Upon counterclockwise movement of Ithe arms I64 and shaftv I65 the flattened portions of the shaft bearingagainst. the arms I40 rock these arms also counterclockwise-to separatethe rollers I39 from the feed roll I31. During this movement studs I66,one oneach of the arms I40,.contact the plate I56 and carry the lattertherewith, the parts being shown in their-moved positions-at I39, I40and I56 in Fig. 11. This provides afree passage for the original sheetI53 between the bar -I55.and plate I56, and between the feed roll I31and the pressure rolls I39.

When the arms I64 are restored clockwise to their normal position thesprings I4I press the' original between the rolls I39 and the feed rollI31. The clockwise movement of the bar I55 is limited by the arms I59striking collars on the shaft I38. Adjustable'stop screws I61 areprovided to limit the clockwise movement of the lever I63, shaft I60 andplate I56 so that as thejparts I appear in their normal position in Fig.11 there is a slight clearance between the bar I55 and plate I56 topermit free movement of the original I53 when line spaced as abovedescribed.

It is important that the ribbon 99, the original copy I53 and the ledgersheet 63 do not come into physical contact until the instant pressure isapplied by the pressure bar 83. The reason for this is that it isdesired to produce a clean copy without smudges or smears which wouldoccur if the sheet I53 touched sheet 63 during movement of either, or ifthe moistened ribbon 99' touched the original sheet I53 before-pressureis applied the solvent would cause the carbon deposit. onjthe back ofthe original term so upon application of pressure a smudged 'copy wouldresult.

In order to avoid this and produce a clean copy these elements arebrought in'toclose proximity but not into actual contact just beforepressure is applied and are quickly separated thereafter.

To accomplish this the mechanism described above and iIlustrated'inIE'ig. does not move the ribbon 99 all the way to transfer position butmoves the arms IIO which carry theribbon to approximately the Positionindicated by dotted lines at 0' in Fig. 6, in whi'ch position the armsIIO lie in the paths of arms I 68( Figs.'5 and 6) pivotally mounted onthe pressure bar 83. Also mounted on the pressure bar 83 are latch pawlsI69 and stretched between arms I68 and pawls I69 are springs I10. EarsI1.I on the pawlsI69 extend beneath the plates"IOI and I02; holding thepawls I69-disengaged from their associated arms-I68 when the bar 831s inits uppermost position.- I My As the pressure bar -93 commences its dwnward movement-the ears I1I move away from the plates "I and I02permitting springs 110 to rock arms I68 until projections I12thereoncome into-con tact with ears I13 on the arms I68. During the continueddownward movem'entof thebar the arms 168 come'into cOntact-Withthe-ribbon arms,

IIIl and, since the springs I10 (Figs. 12' and 13) are of greaterstrength than the spring I32 (Fig;

10) the ribbon arms I I0 are rocked further clock wise to the positionshown infull lines in Fig. '6'.

' Referring to Fig. 11-. the arms-=I59 which carry the guide barI55are"provided with bent portions or ears I14 which extend intot-hepath of travel of the ribbonarms IIO. ---Projections I15'on the ribbonarms I'-I0 come into contact with theseears carrying the arms I59, thebar-155' and conse- V quently'the original sheet-H53 downwardly from thepositionshow'n in Fig. ll 't' o that illustrated in full lines in Fig,6. Justbe'for 'pressureis applied by the platen I24, said platen, theribbon-.99. original I53 and the ledger sheet 63' occupy :the positionsin which they are'shown in' Fig. 6,-where it can be seen that, "whilethese membersare close together, they are slightly separated.-Thepressure on the 'arms I59 also presses the bar I 55 downwardlyagainst the'plate 'I56- to grip'the original sheet I53thus'preventingdisplacement of thissheeta a The movement of the pressurebar -.83 is continuous downw'ard'to applypressure and then upwardly toits normal position. -As the bar continues downwardly from the positionshown in Fig. 6, theiarr'ns I59 and ribbon arms IIO being stopped by theplate 2I,'the arms I68 (Fig. 12) rock to the" position 'shownin Fig. 13,the projections I12 moving under the ears I13.- The purpose of thuslatching the arms I68 in theirmoved position is to prevent the springsI10 from holding the ribbon arms I I0 and the arms I59 down untilthe-arms I68 strike" studs I18; in other words,t'o permit a quickseparation of the ribbon 99,- original I53 and ledger sheet 63 uponcommencement of the upward movement of the bar 83. This quick separationis necessary to prevent smudging and running of the carbon.

. .As the bar 83 nears the end of'its'u'pward stroke the ears "I of thepawls I69 strike. the under sides 7 oftheplates mm m m which assumetheir-normal'positions in readiness for another operation. a

As soon as the pressure'isreleased the mechanism illustrated in Fig. 7moves the ledger ,car-

riage to its original position-and the cam 12 (Pig. 8) raises the barone release the grippers- The operator may now adjust the ledgerposition on the pad ill in' the solvent rwervoir III. "I alsofpermitsthespring Iil wise toclose the'coverl II. a

Also near the end of the operation, the paper feed mechanism- (Fig. 7)operates to feed the original sheet'ili one line space.

ReferringtoFlg. 11, the lever It! extends downwardly below the plate ortable 2i where it cooperates with a rod ill suitably moimted to slidehorizontally in the machine. The lever I83, as set forth above, isrocked counterclockwise upon operation of the arms I 'to release therollers I39 for the purpose of removing the old sheet 3 .and inserting anew one. This movement of lever IE3 thrusts the rod I10 toward the rightopening a pairofcontacts i" which arewired in series with the motor 28.This opens the circuit to the motor to prevent operating the machinewhile inserting a new sheet.
